It is assumed that you do not enable --tollef by accident, and you
only enable it to get compatibility with Tollef's parallel (i.e. you
know what you are doing). That is why there is a warning when you run:

parallel --version
(with --tollef enabled in /etc/parallel/config)

which you - according to documentation - must do before filing a bug report.

I am somewhat annoyed that --tollef gives me more support work.
--tollef was implemented to _avoid_ more support work by providing
backwards compatibility to existing Tollef's parallel users to ease
their migration to GNU Parallel. But if --tollef proves to give me
more support work it might be preferable to retire that option.

I would tend to agree with Ian: If I had explicitly asked to get GNU
Parallel installed I would not expect it to go into tollef mode (It
will be fair to call me biased here).

Did you get your GNU Parallel merchandise?
